' IMPROVEMENT IN MOTORS.

Specification forming part of Letters Patent N 0. 188,529, dated March20, 1877; application filed May 25, 1 -876.

To all whom it may concern:

Be it known that I, EDWARD MGGAFFREY, of Albany, in the county of Albanyand State of New York, have invented certain new and usefuLImprovementsin Motors; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings,

and to letters of reference marked thereon,

A is the connecting rod or shaft, from the I cylinder-piston or othermotive power. B is a vertically-rotating shaft, having a crank, B, uponwhich is pivoted the shaft A. from the motor. 0 is a drum or gear-wheel,by which the power is transmitted to the machinery, and b b are thebearings forv the vertical shaft B, which are secured in the framework Dof the machine. I

Upon shaft B is rigidly affixed a block of iron or other heavy material,E, of the shape of a cube, shaft B passing vertically and diagonallythrough opposite corners. F are tubular reservoirs, secured one uponeach of the slanting sides of cube E, and closed at the top byscrew-caps f, or similar devices. Into these reservoirs I pourquicksilver until one-third, one-half, or nearly quite full, accordingto the weight and impetus it is desired to give the cube E.

When the power is at rest, the quicksilver in the reservoirs F will belevel, as indicated by the line am in Fig. 2 but when the power isstarted, the shaft B and cube E will rotate,

and consequently the quicksilver will be forced in an outward directionby the centrifugal force until, when the machine is. at full speed, itassumes the position indicated by the line 3 y in Fig. 2, thus fillingthe parts of the reservoirs that are farthest from the vertical axis ofcube E, the effect of which is to increase the impetus and power of thema- 7 chine.

When the power is slackened, the quicksilver will gradually return toits level, thus decreasing the force of the rotations of cube E t in thesame degree as the power is slackened.

The advantages of my improvement are as follows: Owing to the verticalposition of shaft B, it requires less force to start the machinery thanwhen the ordinary flywheel upon a horizontal shaft'is employed. The

weight of the balance may, to some extent, be regulated bythe quantityof quicksilver in the reservoir, F, which may be made large enough tohold a considerable quantity; and, finally, when the power is slackenedfor the purpose of stopping the machinery, the quicksilver, returning toits level-line, will aid in gradually stopping the machinery, andprevent the cube E from rotating an undue shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
